Brenda,

Here's a good link that explains LDN....

Those of us with MS use it to treat our disease. And, as you'll read, the dosage is minimal. Usually between 1.5 and 4.0 mg per day.

I've taken it since 8/08 and have found it to be beneficial to me. My first DMD was Copaxone which did not work for me. My second was Betaseron which also did not work for me. I was tired of using harsh chemicals to try and treat my MS. Seems they only gave me additional sx to deal with.

Do your research and choose the therapy that you feel is best for you. Good luck!
